Nagios Support Forum

Hello Team,
I want to know how the npm pm2 (Node process manager) processes can be checked from nagios and monitored on dashboard.
I have tried setting up check_pm2 on the machine which runs pm2 process, but I am not able to identify how we can link this to Nagios XI

The client would need to use an agent like ncpa to run custom scripts. https://www.nagios.org/ncpa/getting-started.php#linux covers installing the agent and https://www.nagios.org/ncpa/help/2.0/active.html has some information regarding to how to run custom scripts.
